"When hired, he informed me that the trimming would be done later in the season and he would alert me beforehand. True to his word, he called about a week before with an estimated date. And again on the morning of. He and one other trimmed and removed as requested. Service was great! Would definitely hire again if needed."

"ATRSTL did an excellent job! They came out when they said they would, trimmed our trees and removed a 7ft hedge. Their team had all the needed equipment and finished the job in a timely manner. All limbs, bushes and debris were cleaned up and taken with them for disposal. Highly recommend!!"

Arborists questions, answered by experts

Whether tree roots will continue to grow after a tree has been cut down depends on the species. Some tree roots will eventually die because they can no longer get nutrients through photosynthesis. However, other species that reproduce through root sprouts can continue to grow and produce new sprouts for seven years or more. For example, the roots of elms, ficus, and willows tend to regrow aggressively, while the roots of pines, oaks, and maples will typically die. To determine if a root system is still active, look for new sprouts on the old trunk, stump, or any exposed roots.

The shepherd’s tree, native to the Kalahari Desert in Africa, holds the record for the deepest known tree roots at over 230 feet deep. Some African communities refer to it as the “Tree of Life” since it provides food, shade, and medicinal properties to the surrounding community.

You can find pruning paints and sealants for trees, but you shouldn’t use them on a topped tree. Coatings like these often inhibit the tree’s healing process. An important exception is if there are dangerous fungi nearby that the tree is particularly vulnerable to, like oaks and oak wilt. Sealing cuts can help prevent fungi from taking root.

Early signs that a tree is struggling include premature leaf shedding and lesions or other strange markings. Peeling bark, dead or rotten branches on the ground, and a conspicuous lack of leaves can all be signs that a tree has started to die. By the time a tree starts leaning, it’s usually too far gone to save.

Your neighbor is not in a good position to know if your trees are truly dead or pose any kind of danger. That’s why hiring an arborist or tree service expert can be such an important part of the process. If the trees are still alive and don’t pose any threat, you’re in the clear (but you may want to document and photograph everything in case events turn sour down the road).

But if a tree is visibly dead and near the property line, you should remove it to be safe. If a dead tree falls on a neighbor’s property, they may have grounds to sue for negligence. If any branches on trees have died, it’s a good idea to cut them back for similar reasons.
